The Dynamically Simple Model for Atmospheric Chemical Complexity (DSMACC) is a tropospheric chemistry box model designed to help understand the composition of the troposphere in a flexiable and friendly manner. It is written to address a range of problems ranging from calculating the expected concentrations of atmospheric radicals to comparing chemistry schemes.
Instructions of the use of DSMACC are provided here
The original code development was by Mat Evans and Kathryn Emmerson at the University of Leeds. Subsquently developement / testing work has been undertaken by Barron Henderson (UF), Dylan Millet , Michael Berkley (U. Edinburgh), and Daniel Stone (U. Leeds). The interface for GEOS-Chem was developed by Jingqiu Mao (Harvard) and Mat Evans.
The DSMACC model code and testcase is available from here. It is based on the KPP chemistry integration code written at Virginia Tech by Adrian Sandu's group.
